Maintenance

Your device provides reliable and efficient operation with a minimum of care. Although specific maintenance is not required, the
following periodic checks ensure dependable operation:

Cleaning the Device

Reading performance may degrade if the scanner's window is not clean. If the window is visibly dirty, or if the scanner isn't
operating well, clean the window with a soft cloth or lens tissue dampened with water (or a mild detergent- water solution). If
a detergent solution is used, rinse with a clean lens tissue dampened with water only.
The scanner housing may also be cleaned the same way.

Inspecting Cords and Connectors

Inspect the interface cable and connector for wear or other signs of damage. A badly worn cable or damaged connector
may interfere with scanner operation. Contact your distributor for information about cable replacement. Cable replacement
instructions are on

Replacing Cable in the Scanner

The standard interface cable is attached to the scanner with a 10-pin modular connector. When properly seated, the connector
is held in the scanner by a flexible retention tab. The interface cable is designed to be field replaceable.
• Order replacement cables from Honeywell or from an authorized distributor.
• When ordering a replacement cable, specify the cable part number of the original interface cable.

Troubleshooting the Scanner

The scanner automatically performs self-tests whenever you turn it on. If your scanner is not functioning properly, review
the following Troubleshooting Guide to try to isolate the problem.
